Git reset head8/31/2023 Whether this status was unintended and you want to "fix" the 'detached HEAD' or not, you can go back to the branch you're supposed to be on by running the git checkout order. "You're in the 'detached HEAD' state" is not an error message, and there are zero worries.Īs I mentioned earlier, this status means that you are no longer in a Git branch. If you switch branches with the git checkout command at that point, your modifications will be lost. Having no branch, you could miss all your work completed to fix some problem, as you can not merge your code into a main or with any other git branch. Technically, you can not save any work in your repository. It means any commits made after that won't belong to any git branch. And, Git will not put the HEAD in the branch. And, with that, you can continue to work without any difficulties.Īnd, if you check out a particular commit, you are already in a detached HEAD state. When you are trying to checkout a git branch, HEAD points to the top of that branch. The HEAD in Git is the current branch on which you're working on. It may also be used from there to travel to distinct points of history and function.Changes from the last point visited will be used to create changes.It is used to refer to the branch recently committed.head in a phrase: HEAD in all caps is a reference or commit that you are accessing in your repository, while a "head" without caps is “head” that you are not viewing. There could be a variety of heads in a repository, but just one HEAD. For example, "main" is a "head" since a branch is a reference to it. It may refer to all of the "heads" in a repository while "head" is written in lowercase. In lowercase, you can see "head" printed. Note: to signify this status, we have used all capital letters. The HEAD is the branch (or a commit) you are now looking at. In my case, it’s pointing to the main branch, so the following output will appear on the shell:Īnd, if you are interested in the commit hash Id on which head is pointing, you can use the following command to display it: You can see where the current Git HEAD is pointing to with the following command: The default used is 1, if no number is mentioned, so HEAD~ is equal to HEAD^. The tilde (~) is a shorthand character for a row of several characters (^).Īnd, in the same way, the equivalence of HEAD~3 to HEAD^^^. The Caret (^) is the parent of the Commit. More specifically, HEAD is a moving pointer that may or may not refer to the current branch, but it always refers to the current commit. In other words, the HEAD is a pointer to the parent of the next commit or where the next commit will occur since it is where the repo left off. In the repository, HEAD points to the starting point of the current branch at all times. HEAD is a reference to the last commit in the current check-out branch. Whenever you check out a branch or create a new branch, Git HEAD transfers it. In simple terms, you can say Git HEAD is the current branch. When you use the git checkout branch, HEAD points out the last commit. There are many git commands that you can use to manage your branches in git. Git branches are super helpful, and you can create a new branch, merge a branch, or delete a branch, per your requirements. You will learn about the detached head and how you can reset it with a few simple git commands. In this Git HEAD guide, I will explain all about the basics. In case you need a downloadable pdf copy, you can get it here. Recently, I published a detailed guide about Git reset HEAD.
